## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402stock-hip-3-dex-synthetic-perp-markets-data-b05824be
```

Example prompt: Pull the live synthetic perp market data from the XYZ builder DEX on Hyperliquid — I want to see current mark prices, funding rates, and open interest for all their markets right now.

## When to prefer this

Use this endpoint when you need real-time on-chain perpetual market data (prices, funding, OI, volume) for synthetic assets traded on a specific Hyperliquid HIP-3 builder DEX. Prefer this over traditional market data APIs when you need 24/7 availability including weekends, on-chain transparency, and no account or API key setup — just pay per call in USDC. This is specifically for HIP-3 standard builder DEX perps, not for Hyperliquid's native order book or spot markets.

## Known failure modes

- Invalid or unknown DEX identifier returns an error or empty markets array
- DEX temporarily offline or no active markets results in empty response
- Stale oracle data may cause price divergence from underlying asset
- Payment in USDC via x402 on Base required; missing or failed payment results in 402 response
- Rate or liquidity data may lag during low-activity periods

## How this service works

Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.

## Output

A JSON object listing all synthetic perpetual markets on the specified HIP-3 Hyperliquid builder DEX, including for each market: symbol, mid price, mark price, oracle price, premium, funding rate (hourly and APR), open interest, day volume in USD and base units, max leverage, and previous day price. Also includes DEX metadata (deployer address, DEX name, standard, market type) and a disclaimer clarifying these are synthetic oracle-priced perps, not official exchange prices.
